Fig. 2 is the flow chart that schematically shows an embodiment of method of carrying out pacing for the respiratory activity to object of the present invention; And
Fig. 3 and 4 is diagrams of diagram pacing speed according to an embodiment of the invention progress in time.
The specific embodiment
The breathing pacing system of Fig. 1 is provided as sense of touch and breathes pacing system 10, and it comprises the profile of decision pacing system 10 and the sense of touch output unit 12 of outward appearance.As the back will further describe, all functions assembly that pacing system 10 is breathed in sense of touch all is integrated in this sense of touch output unit 12.It only is a example according to breathing pacing of the present invention system that pacing system 10 is breathed in sense of touch, and its sense of touch output unit 12 can be substituted by any other suitable output unit of the output signal of object perception by being used for generating, and is for example substituted by acoustics output unit or vision output unit.The description of back will be referred to sense of touch and breathes pacing system 10, but scope of the present invention is not limited thereto.
In this example, sense of touch output unit 12 can be medicated cushion, medicated pillow, liner, stuffed toy, mobile phone, wrist strap or wrist-watch, but it can have different types of shape and size.These examples are not appreciated that and limit that opposite sense of touch output unit can have any other suitable size or shape.Corresponding output unit 12(is such as medicated cushion or liner) be provided as its size of periodic variation (particularly its thickness), and this change is can be by the sense of touch output signal of the object perception that closely contact with sense of touch output unit 12.Sense of touch output signal by 12 outputs of sense of touch output unit is used for the respiratory activity of object is carried out pacing.Under the situation of portable terminal or wrist-watch, can use vibrating function.
Replacedly, the pneumatic sensor that is used as sensor 14 in this embodiment can be substituted by the body kinematics sensor in order to the respiratory activity of monitoring target.This embodiment is based on following idea: respiratory activity causes the periodicity of subject's body to move, and periodically movement can be easily by the body kinematics sensor measurement for this.Accelerometer is in order to move an example of the body kinematics sensor of determining breathing rate from chest or abdominal part at this type of.Compare with pneumatic sensor, the advantage that the body kinematics sensor provides is that it can be integrated into fully in the sense of touch output unit 12 and can't tap into from the outside.When not measuring in the special time amount when mobile, this state can be interpreted as the situation that object and sense of touch output unit 12 do not contact, and sense of touch is breathed pacing system 10 and can be automatically shut down.This also is possible in the embodiment that uses pneumatic sensor, does not wherein have input (namely not measuring air-flow) to be interpreted as sense of touch by pneumatic sensor in the special time amount and breathes the situation that pacing system 10 is not used.
The body kinematics sensor can also comprise the motion detector of the form that adopts drop conduction of current material, move between the position that it can flow at the electric current between the promotion electrode and the position that does not have electric current to flow, thereby electric current is subjected to the modulation of the movement of described drop.As previously mentioned, such mechanism can be used to close down sense of touch pacing system 10 or be set standby mode when modulation does not take place.
Another embodiment of sensor 14 is in order to the photoplethaysmography (photopletysmograph) of breathing style from the analysis of blood volume pulse signal (PPG).In a common embodiment, subject's skin (for example skin on finger or the wrist) is thrown light on, and measure the change of the light absorption that causes owing to respiratory activity.The user can be placed on by the finger with s/he on the window of the surface that is present in sense of touch output unit 12 and operate photoplethaysmography.
Alternatively and/or additionally, can use to be arranged on the motion that outside radar sensor is measured health, thereby derive the input signal relevant with breath signal.Another embodiment of long-range body sensor like this is weight or pressure transducer, and it is for detection of the mechanical pressure that is applied corresponding to the respiratory activity of s/he by object.Such sensor can comprise the presser sensor coil.
Also might use camera as sensor for this reason.
Other operating units that pacing system 10 is breathed in sense of touch have signal analysis unit 16 and actuator 18, and the two all is integrated in the sense of touch output unit 12.The input signal that signal analysis unit 16 receives from the breathing rate that shows object of sensor 14.Sensor 14 generates this breath signal according to measured breathing rate.Signal analysis unit 16 is provided to analyze input signal, and seeks the signal aspect that is included in the input signal.In addition, signal analysis unit 16 also is provided to control actuator 18 according to the result of described analysis, as the back will as described in.Actuator 18 is provided to cause the movement of sense of touch output unit 12, thus output sense of touch output signal.That is to say that sense of touch output unit 12 moves according to the movement of actuator 18, and this motion can be by the object perception.For instance, sense of touch output unit 12 increases or reduces its size or can change its profile.But also can include the appreciable change of other senses of touch of the outward appearance of sense of touch output unit 12 or interior sight in consideration.Sense of touch output unit 12 can also implement sense of touch appreciable knock or other power effects so that for the user provides appreciable signal, this for example is owing to the turning motor that may provide additional frequency regulator information is realized.
The rechargeable power supply (not shown) that pacing system 10 can also comprise rechargeable battery for example or accumulator and so on is breathed in sense of touch.So just make pacing device under the situation that need not any connection of making us bothering that goes to mains supply, to carry out radio operation, thereby further improve its user friendly.
When generating input signal, sense of touch output unit 12 is activated to export the sense of touch output signal sequence.In the present embodiment, when the signal aspect that in input signal, picks out as breath signal, generate these initial signals by signal analysis unit 16.This means that at least one respiratory characteristic (for example breathing rate) has been identified as input signal.If this is the case, then signal analysis unit 16 control actuators 18 are initiated the sense of touch output signal sequence, and it comprises the signal aspect relevant with the signal aspect that picks out.For instance, these sense of touch output signals have and the same or analogous frequency of measured breath signal or amplitude.Another kind of probability is that the signal aspect of the sense of touch output signal that generates has particular kind of relationship with the signal aspect that picks out.As just an example, the sense of touch output signal frequency can be a little less than measured breathing rate.In addition, the expansion of actuator and the ratio between the contraction time can be different from slightly by the measured air-breathing and expiration ratio of respiration pickup.Signal analysis unit 16 can comprise in order to correspondingly to control the computer program of actuator 18.
Have the sense of touch output signal sequence of the signal aspect relevant with the signal aspect that picks out by generation, might be synchronized to the sense of touch output signal that generates user's current breathing behavior.In the present embodiment, up to the signal aspect that is picked out by signal analysis unit 16 in the input signal, sense of touch output unit 12 just generates the sense of touch output signal.In case pick out after the style, just generate initial signal so that the output of sense of touch output unit 12 beginning sense of touch output signal sequences.Also begin to generate the sense of touch output signal under the situation of the influence of the measurement that might during not being subjected to the initially monitoring stage, carry out, and basis is stored in the intrasystem output that begins the sense of touch output signal sequence from the signal aspect that picks out in previous monitoring stage when initial signal is arranged.
Input block as additional provides mouse roller 20 in the surface of sense of touch output unit 12.Mouse roller 20 is integrated in the sense of touch output unit 12, thereby it can be tapped into from the outside.The user interface that mouse roller 20 represents in order to the characteristic of regulating the sense of touch output signal sequence.For instance, the user can select and/or regulate respiratory frequency or amplitude with as the input signal that is used for signal analysis unit 16.Another function of mouse roller 20 can be to generate initial signal when being pressed by the user, in order to initiate the output of sense of touch output signal.For instance, when the user had finished the adjusting rules, s/he presses mouse roller 20 so that the beginning pacing.In the same way, the user can stop the output of sense of touch output signal by pressing mouse roller 20 again.
Should be mentioned that mouse roller 20 can represent at a kind of alternative that sensor is provided, that is to say user interface can alternative sensor with as the input block that generates the input signal that is used for signal analysis unit 16.But also might whole two function combinations of user interface and sensor in an input block, perhaps provide the different input blocks that generate the input signal that is used for signal analysis unit 16 respectively.Thereby can generating portion ground based on the sense of touch output signal of the measurement of the user's input that obtains via user interface and the object-based breathing behavior of another part.For instance, at least one characteristic of described sense of touch output signal can be set according to his identity and/or other people's situations (such as his age) by the user.This characteristic can be used to set the situation that the sense of touch output signal when beginning is handled in pacing.The measurement result that obtains by sensor can be used to regulate and revise described sense of touch output signal sequence during pacing is handled.Signal analysis unit 16 can also use previously stored parameter, characteristic or algorithm to calculate the sense of touch output signal.
Flow chart among Fig. 2 shows corresponding to a kind of situation that generates the pacing Signal Processing.The hypothesis input signal is only generated by sensor 14 in the description of back.By sensor 14(as shown in fig. 1) measure the respiratory activity of (step 100) object, in order to generate the input signal (step 110) of the respiratory characteristic (such as breathing rate) that shows object.This input signal representative comprises air-breathing and periodic breathing activity expiration phase.Subsequently input signal is sent to signal analysis unit 16 to analyze (step 120).In this is analyzed, the signal aspect that signal analysis unit 16 is sought in the input signal.In case the style of picking out just generate the initial signal that is used for actuator 18, and sense of touch output unit 12 is activated (step 130) in order to begin the output of sense of touch output signal sequence.At least when this sequence began, the sense of touch output signal comprised the signal aspect that picks out corresponding to the input signal of being analyzed by signal analysis unit 16 in step 120.
A kind of probability is as a reference to be used for generating the sense of touch output signal air-breathing and expiration ratio.Observation shows that the air-breathing and expiration ratio less than 1 is of value to be loosened.If the current air-breathing and expiration ratio of object for example is identified as greater than 1 or equals 1, then sense of touch output unit 12 can be exported such sense of touch output signal sequence, it starts from the expansion time (this is natures for most of people) corresponding to the current inspiratory duration of object, but contraction time is longer than expiratory duration.Therefore frequency regulator speed starts from being lower than the frequency of measured respiratory frequency.The contraction that should be mentioned that sense of touch output unit 12 is related with expiration phase (thereby the expansion of handle assembly and expiratory phase are related) not necessarily, shrink role with expansion but can reverse.
As previously mentioned, input signal can be can't help sensor 14 and be generated, but can also be derived from user interface as input block to be used for regulating the characteristic of sense of touch output signal sequence.For instance, the user regulates personal breathing characteristic (frequency, amplitude etc.) about identity and the individual situation of s/he by mouse roller 20.This can be interpreted as input signal by signal analysis unit 16 in the step 120 of Fig. 2, and according to the result of this analysis, the output of sense of touch output unit 12 beginning sense of touch output signal sequences.
As a kind of alternative, the input signal of sensor 14 and user interface (being mouse roller 20) can be included into consideration.For instance, the user can import foregoing personal breathing characteristic so that the prerequisite of determining to handle corresponding to pacing.The current respiratory activity that sensor 14 can monitoring target subsequently, and signal analysis unit 16 will calculate the sense of touch output signal sequence based on whole two kinds of input signals.
For the guiding at respiratory activity is provided, preferably based on length and the frequency (referring to Fig. 3) in each stage in the calibration data that obtains (the perhaps calibration data that obtains during operation period formerly) the control sense of touch output signal sequence, thereby make relaxation effect take place.Signal analysis unit 16 can determine the further progress of described sequence, and it starts from the frequency corresponding to the respiratory frequency that picks out, and changes described frequency in the further process of sense of touch output signal.
Diagram among Fig. 3 shows a kind of possible situation about the time sequencing progress of the pacing speed (frequency) of sense of touch output signal.Illustrated trunnion axis express time among Fig. 3, vertical axis is then represented pacing speed.Time shaft is divided into 5 different phases, and the phase I starts from t (1)=0 and is calibration phase (P1), wherein sense of touch output unit 12 be do not activate and do not export the sense of touch output signal.Calibration phase (P1) is stage (P2), (P3), (P4) and (P5) afterwards, wherein sense of touch output unit 12 be activate and output sense of touch output signal sequence.Starting from initial period (P2) this activity cycle, is thereafter decelerating phase (P3), constant pacing speed stage (P4) and diminuendo stage (P5).
In calibration phase (P1), by the respiratory activity of sensor 14 monitoring targets that generate input signal.This input signal is analyzed by signal analysis unit 16.By this monitoring, breathing process that can analytic target, thus obtain expressing the curve of respiratory activity.Figure 3 illustrates the different curves as three examples of the progress of the breathing rate during the calibration phase.
One " breathing rate profile " of each bar curve representation object.Signal analysis unit 16 can be derived the starting point of pacing activity, the suitable pacing speed when namely the sense of touch output signal sequence begins from this profile.Pacing speed (frequency) only is that of the sense of touch output signal that can select may characteristic.Another characteristic can be the pacing amplitude that also derives from the measurement result of calibration phase (P1).In general, signal analysis unit 16 attempts finding the signal aspect in the breathing profile of being represented by input signal, and when picking out such style, generates the initial signal that is used for actuator 18 in order to export the sense of touch output signal relevant with this signal aspect.
Might when the signal aspect of search in the input signal, confirm the result in previous monitoring stage in addition.This means that the calibration phase shown in Fig. 3 (P1) only is an example in such monitoring stage, wherein the sense of touch output unit does not activate.But such monitoring stage also can be represented by the previous operation cycle that pacing system 10 is breathed in sense of touch, wherein monitor the respiratory activity of object.Should be mentioned that also calibration phase (P1) before output sense of touch output signal sequence is may be not always unnecessary.But can only select the starting point of pacing activity based on foregoing historical data (being the previous operation cycle).
When picking out signal aspect and having generated input signal, in the beginning of initial period (P2), described pacing starts from the base level f (1) of pacing speed at time t (2).During this stage (P2), reduce slightly in the present embodiment of pacing speed in Fig. 3 of sense of touch output signal.This process that reduces (slope of a curve of namely representing time dependent pacing speed) also can depend on calibration result.Also might during this stage (P2), keep the pacing constant rate.Initial period (P2) is decelerating phase (P3) afterwards, and wherein pacing speed reduces more tempestuously up to time t (4).During this decelerating phase (P3), pacing speed is reduced to f (3) from numerical value f (2).This numerical value f (3) is corresponding to the target breathing rate of desired respiration sequence, and the respiratory characteristic that can measure during the calibration phase is derived.According to an example, pacing speed f (3) can be corresponding to 60% numerical value of the breathing rate that records when initial.
Decelerating phase (P3) is the constant pacing speed stage (4) afterwards, and wherein pacing speed keeps constant at horizontal f (3).Can come the length of calculation stages (P4) based on previous monitoring periods, i.e. previous operational phase and (also having alternatively) calibration phase (P1) of pacing system 10 breathed in sense of touch.In the decelerating phase (P3), pacing amplitude (not shown) can increase to specified level linearly, and can remain on this level during the stage (P4).During the stage (P2) to (P5), can also change other characteristics of sense of touch output signal according to predetermined way.
Stage (P4) is the diminuendo stage (P5) with the constant pacing speed that is in horizontal f (3) afterwards.In the stage (P5), the pacing amplitude can be reduced to zero, thereby the pacing activity is located to finish at time t (6) in this embodiment.
Though can decide stage (P4) and length (P5) based on monitoring result as previously mentioned, also can be based on whether having the input that enters sensor 14 to decide its length.When sensor did not generate input signal (cyclical signal that namely shows the breathing rate of object), then this can be regarded as showing between object and sense of touch output unit 12 and not contact, and sense of touch is breathed pacing system 10 and is not used.So might begin the diminuendo stage (P5) or thoroughly finish the pacing processing.
Can stop pacing when definite object has been fallen asleep or relax to desired degree handles.When in input signal, picking out particular characteristics or signal aspect, can begin the diminuendo stage (P5), perhaps close stop system in this case immediately.For instance, sensor 14 can measure respiratory frequency, amplitude or the air-breathing and expiration ratio that shows weak respiratory activity, thereby shows the state that object is sleeping or the degree of depth is loosened.The corresponding signal style that is derived from the input signal of sensor 14 will be picked out by signal analysis unit 16, and it will generate the stop signal that is used for sense of touch output unit 12, in order to stop the sense of touch output signal sequence immediately, the wherein pacing amplitude that perhaps begins is reduced to for zero diminuendo stage (P5), and whole system is turn-offed.In this embodiment, signal analysis unit 16 is provided to based on may be corresponding to the length of the input signal characteristics control sense of touch output signal sequence of the particular condition of object.
A kind of possible pacing situation has only been described in the front.Another kind of probability is to exempt calibration phase (P1), and only breathes the previous operation cycle derivation breathing rate profile of pacing system 10 from sense of touch.This means previous life cycle as the monitoring periods of detection signal style therein.
The third situation is not only to confirm the input signal that generated by sensor 14, but also confirms to be derived from the input signal of the user interface of mouse roller 20 among Fig. 1 for example and so on.For instance, the user can regulate or select the personal breathing characteristic as previously mentioned, in order to determine the prerequisite of handling at pacing and be entered in the user interface.Such personal characteristics can refer to user's identity, age, sex or other individual characteristicss.This input can be used as input signal subsequently, to be used in the beginning of sense of touch output signal sequence a certain pacing characteristic being chosen as " starting point ".In the further pacing process of stage in Fig. 3 (P2) during (P5), can be based in calibration phase or formerly, coming tuning (namely further adaptive) described sense of touch output signal sequence as the sensor signal of history data collection in the operational phase.
In all these situations, might generate stop signal in order to stop sense of touch output unit 12 and further produce the sense of touch output signal.As previously mentioned, stop signal can be generated when picking out the signal specific style that is included in the input signal that is derived from sensor 14 by signal analysis unit 16.But also can include other factors in consideration, running time of sequence for example, thus could generate stop signal up to having passed through predetermined period of time.Also might only generate stop signal on the basis of time, that is to say the persistent period that a fixed time period is defined as described sequence, perhaps import to determine according to the user who obtains by user interface.In this embodiment, signal analysis unit 16 is provided to based on the length that can be programmed and/or can be controlled by the time scheduling table that the user changes the sense of touch output signal sequence.
Might be by influencing output signal by the input block of object active operation in this version.Can allow the user between about the specific prerequisite that generates the sense of touch output signal, to select, for example between the slower or very fast respiration sequence of beginning place of initial period (P2), select.But the influence of the signal aspect that had before picked out still can be arranged, thereby still can adapt to user and personalized to a certain extent to the sense of touch output signal sequence that generates.
Though shown in the present embodiment in Fig. 1, might not breathe pacing system 10 for sense of touch display device is provided, it demonstrates the mode of operation that pacing system 10 is breathed in sense of touch to the user.Such display device can be the light source of visual displays, for example LED and so on or the audio frequency display device that provides sound feedback for the user.This display device also can be arranged on the outside, thereby it is not integrated in the sense of touch output unit 12.
